Anthraquinone compounds for textile dyeing and antileukemia agents: Anthraquinone compounds for textile dyeing and antileukemia agents. (Allied Chemical Corp., USA). Belg. BE 857494 6 Feb 1978, 23 pp. Addn. to Belg. 855,088. (French). (Belgium). CODEN: BEXXAL. CLASS: IC: C07C. APPLICATION: BE 77-855088 26 May 1977. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 26 Anthraquinones I (X = C1-4 alkylene) were prepd. Thus 121 g 2,3-dihydro-1,4-dihydroxyanthraquinone [17648-03-2] was treated with 124 g H2NCH2CH2NHCH2CH2OH [111-41-1] with aeration to give 138 g I (X = CH2CH2) [64862-96-0]. At 62.5 mg/kg daily for 9 days i.p. in mice, infected with leukemia L-1210, I (X = CH2CH2) increased survival time 21.8 days, from 9.9 days for controls.

Novel human hair dyes: Novel human hair dyes. I. Kikuchi, Masashi; Matsuoka, Masahiro; Nakano, Motokiyo (Shiseido Basic Res. Lab. 17648-03-2 and 5690-27-7 are also occured in this study., Yokohama 223, Japan). Sen'i Gakkaishi, 43(3), 144-7 (English) 1987. CODEN: SENGA5. ISSN: 0037-9875. DOCUMENT TYPE: Journal CA Section: 62 (Essential Oils and Cosmetics) The dyeability of naphthoquinone vat dyes was investigated using wool as a model of human hair fibers. Leuco-naphthazarin (I) [5690-27-7] dyes wool fibers effectively in an aq. soln. under exceedingly mild conditions without any reducing agents and strong alkali in a dyebath at room temp. The color development can be also achieved without any oxidants. The degree of exhaustion was 70.2% at 30° for 2 h. Wash-fastness was excellent and the dye on the fibers was not removed at all in 25% aq. pyridine soln. under refluxing condition. Contrary to leuco-naphthazarin, the sorption of leuco-quinizarin [17648-03-2] did not take place at all. .
